Answer:
2.638, 3.16, 3
, 
Step-by-step explanation:
Convert all the numbers as a decimal, this will make it easier to determine which value is greater or not.
Have a great day :)
It’s 43 cm because you add all the sides
Ok
so the focus is on the opening side of the parabola
so for a vertex of (h,k)
opening up and down
(x-h)²=4p(y-k)
p is the distance from vertex to focus
it is also the distance from the vertex to the closes point on directix
2p=distance from focus to directix
p is positive if the focus is above the directix
ok
y=9 and (7,6)
9>6
directix is above the vertex
p is negative
find distance
from 9 to 6 is 3
3=2p
1.5=p
p is negative
and the vertex will be 1.5 above the focus and 1.5 below the directix
vertex is (7,7.5)
(x-7)²=4(-1.5)(y-7.5) is de equation
Surface Area of Cube = width^2 * 6 (sides of the cube)
Therefore, (3.5)^2 * 6 =
73.5 [whatever units]^2
The angle RSV would be 42°
